One of the victims in the Georgetown Road car accident on Wednesday night has died.

Jerome Kilty, 90, of Hillside Road North in Weston, a renowned actor and playwright, died today at Norwalk Hospital of cardiac arrest, according to Weston Police Chief John Troxell.

Mr. Kilty was one of two drivers injured in a two-car crash around 5:15 p.m., on Wednesday, Sept. 5. The other driver, who has yet to be positively identified because he was not carrying identification, is presently in serious condition at Norwalk Hospital. The vehicle the unidentified man was driving is registered to Balvin Petgrave of Bridgeport. Police say they are trying to determine if it was Mr. Petgrave at the wheel.

Police reconstructed the accident scene after closing Georgetown Road for several hours following the crash, and believe Mr. Kilty was driving down Hillside Road North when his car crashed into the Petgrave vehicle headed northbound on Georgetown Road. Mr. Kilty’s car appeared to have plowed into the side of the other car without stopping at the stop sign on Hillside Road North, Chief Troxell said. The actual cause of the accident is still under investigation, and it is not yet known if the cardiac arrest Mr. Kilty suffered occurred before or after the crash.

When police arrived on the scene, they found Mr. Kilty lying on the road. Both drivers were treated by Weston EMS on the scene before they were transported to Norwalk Hospital.

Mr. Kilty was both a celebrated playwright and actor. His plays include Dear Liar: A Comedy of Letters, adapted from the correspondence between George Bernard Shaw and Mrs. Patrick Campbell, Dear Love, based on the poems and letters of Robert and Elizabeth Barrett Browning, and The Ides of March.

As an actor, he appeared on Broadway in Mastergate, Quadrille, and A Moon for the Misbegotten, for which he was nominated for a Tony Award. He appeared internationally in many shows and was in the cast of the first international tour of Edward Albee’s Who’s Afraid of Virginia Woolf.

In 1948, Mr. Kilty co-founded the Brattle Theater Company in Cambridge, Mass. He also appeared on early television shows such as Kraft Television Theatre, Studio One, and Hallmark Hall of Fame.

He was predeceased by his wife and touring co-star Cavada Humphrey in 2007.
